A SMALL JAR OF LIVING MOSS
A good first step into keeping moss. Choose feather, bun or a seasonal mix, layer it into a lidded glass jar, and the jar recycles its own moisture so the moss stays soft and green with very little attention.
- In the kit: fresh live moss in your chosen style, a glass jar with metal screw lid (black or copper, subject to availability), terrarium substrate, clay-pebble drainage layer and care and assembly instructions
- Build time: about 15–20 minutes, no experience needed
- Care: it's a closed jar, so it needs very little watering once settled; keep it out of direct sun
- Delivery: Free across the UK. Gift wrapping available.
A SMALL STORY
A nine-year-old was told she could have one pet. After a long negotiation, she chose a jar of moss. Her parents were relieved, then puzzled, because every morning at breakfast she gave a weather report from inside it. Fog on the glass meant a rainy day in there. Clear glass meant sunshine. A few drips running down the side was a storm, and the moss was "fine, just dramatic." The forecasts have kept going ever since, delivered with complete seriousness. Nobody has asked for a dog.
CHOOSE YOUR MOSS
Feather Moss — loose, branching and naturally varied, creating the appearance of a miniature woodland floor.
Bun Moss — rounded, compact cushion moss that creates a more defined, sculptural little landscape.
Mixed Moss — a small seasonal mix of live moss pieces, hand-selected for whatever is looking healthiest when your order is packed. It may include rounded cushion-style pieces alongside other textures, so every jar is a little different. It's the same seasonal selection as our Mixed Moss Tub.

ADD THE FINISHING TOUCHES
Brass Frog (+£5): a tiny solid-brass frog to sit in the moss. Purely decorative, but it adds a bit of character.
Mini Mister (+£6): rechargeable, with a fine spray that keeps moss lightly damp without flattening it. Or add both for £11.
A GIFT FOR A PLANT LOVER
Add one of our moss colouring books and the kit becomes a proper present: something living to build, and something slow and absorbing to colour while the moss settles in. Choose The Secret Life of Moss for tiny forests and terrariums, or The Darker Side of Moss for abandoned places slowly taken over by moss. A book added here costs £7 instead of the usual £9.99.
About our feather moss
Our Feather Moss is a seasonal selection of living mosses chosen for their soft, spreading growth rather than one guaranteed species, so texture and shades of green change through the year. Take a closer look at Feather Moss in our guide →
How to build it
Each component arrives separately packed. Add the drainage layer first, followed by the substrate. Arrange your chosen living moss on top, give everything a gentle mist and add the lid. Clear instructions are included.
Building it with children
This little jar is one of our most popular family builds. Our guide to making a terrarium with a six-year-old walks through each step, including which jobs to hand over and which to keep for the grown-ups.
Caring for your moss terrarium
Keep the finished terrarium somewhere cool with bright, indirect light and away from strong direct sunlight or radiators.
Because the jar is closed, moisture is recycled inside the terrarium and it should require relatively little watering once established. Keep the moss lightly moist rather than soaking wet. Here's how a closed terrarium waters itself.
A natural, living product
Real moss isn't uniform. Colour, shape, texture and growth will vary naturally, and occasional brown material is part of the normal renewal cycle of living moss. That also means the terrarium you make won't look exactly like the photographs — or anybody else's.
Giving it as a gift
This isn't a ready-made decoration. The recipient gets to build it themselves and then watch the moss settle in. It makes an easy gift for anyone who likes having plants around, and gift wrapping is available if you're sending it straight to someone else.
Frequently asked questions
Does the terrarium arrive assembled?
No. The components arrive separately packed so you can build and arrange it yourself. Instructions are included.
Is the moss alive?
Yes. All three options — Feather Moss, Bun Moss and Mixed Moss — contain fresh living moss rather than preserved or artificial moss.
Do I need terrarium experience?
Not at all. The kit is designed for beginners and includes everything you need to assemble and care for your moss terrarium.

Bought as a Christmas gift, so I haven't seen it. My friend says it is gorgeous and is very happy with it.
I was very delighted with the plant
